摘　　要：介绍了可应用于无线移动通信中的双工器的设计原理和方法。该双工器采用微带抽头发夹型结构,由两个窄带带通滤波器(BPF)通过适当的匹配电路组成。给出了这两个带通滤波器的详细设计步骤,介绍了抽头线位置等的确定方法,提高了抽头线发夹型滤波器设计初始值的精确度。设计仿真结果与实际测量结果吻合良好。The fundamental principle of the diplexer in the mobile communication system and the method for the design are proposed in this paper. This diplexer adopts microstrip hairpin - line structure. It is composed of two narrow bandpass filters connected with proper matching circuits. The detailed design procedure of this filter is introduced and such considerations as the tapped line location are also presented, by which the accuracy of initial design is elevated, The simulation results and the measured outcome match well.
